Rich Hickey

Rich Hickey is a computer programmer and speaker, known as the creator of the Clojure programming language. Clojure is a Lisp dialect built on top of the Java Virtual Machine.^[1][2] He also created or designed ClojureScript and the Extensible Data Notation (EDN) data format.

Before Clojure, he developed dotLisp, a similar project based on the .NET Framework.^[3] Hickey has also worked on scheduling systems, broadcast automation, audio analysis and fingerprinting, database design, yield management, exit poll systems, and machine listening.^[4]

He spent about 2½ years working on Clojure, much of that time working exclusively on Clojure without external funding, before releasing it to the world in 2007. In 2012, Datomic, a proprietary distributed database was launched which coincided with the incorporation of Cognitect.^[5] From 2013 until 2020, he was the chief technology officer of Cognitect.^[5] Cognitect was acquired by Nubank in 2020, and he was a Distinguished Engineer at Nubank until August 2023 when he announced^[6] his retirement from commercial software development.
